IMPROVEMENT IN MACHlNES FoR MAKING HORSESHOE-NAILS.

Specification forming part of Letters Patent No. 124,771, dated March 19, 1872.-

SPECIFICATION.

I, JOSEPHSTONE, of Batavia, in the county of Kane and State of Illinois, have invented a new and useful Improvement in Horse-N ail Machines, of which the following is a specification, reference being had to the accompanying drawing.

The Nature and Object of my Invention.

My invention relates to that class of horse the hook Q and the cutter S, arranged and operating to draw the point of the nail to the center, and to cut off any sharp point that may be left on thenail by the cutters D and G, as hereafter described, thereby giving the nailpoint a more complete finish than has heretofore been done and my inventionfurther consists in the combination and arrangements of the several parts, hereinafter fully described, that operate the hook Q simultaneously with the cutters E and D, noiselessly and with a very little friction.

Description of the Drawing.

Figure 1 represents a side elevation of that part of a horse-nail machine to which my invention relates; Fig. 2, a top or plan view of the same; Fig. 3, an end view; and Figs. 4, 5, and 6, a side view of the nail in its different 1 stages of being pointed.

General Description.

A is the base frame of the machine; 13, the rock-shaft, driven in the ordinary way and O, the arm that carries the vibrating cutters D and E. F is the ordinary anvil or block, to which is attached the stationary or fixed cutter G. These parts are the same as shown in machines now in use; and the nail-rod, represented by the dotted lines H, is held and fed to the cutters obliquely, the same as in other machines in use. I is a vibrating arm or lever, pivoted at J and having one end attached to the arm 0, by which it is vibrated, and the other so connected to the bar K as to give it ahorizontal motion, as hereafter described, when the lever is vibrated. The bar K is suspended on the hangers P, which swing from the crosspiece V, as indicated by the dotted lines. The cross-piece V is rigidly attached to the post or upright U. R is a spring, resting against the end of the bar K to throw it forward. Q is the hook that hooks over the point of the nail after it is thrust forward from the forging part of the machine and before it is severed from the nail-rod. The nail, inbeingforged, is drawn out sufficiently to extend more or less past the hook (B when it is thrust forward. The hook begins to pull against the point of the nail as the cutters D and Gr begin to shearthe metal from the side of the point, and the point of the nail is graduallybent by the pulling of the hook, so that, just as the said cutters are done cutting, there by forming a more complete point to the nail than is formed by forging, the hook has bent the point to the center of the nail. These cutters, in making the shearing-cut of the metal from the side of the point of the nail, leave a fine wiry point at the lower side of the point of the nail, which may still be attached to the metal cut from the nail in forming the point. The cutter S is so pl aced that the hook, just as the cutters D and G finish cutting and thepoint of the nail is bent to its center, presses this fine wiry point against it, and by cutting it off makes a more finished point to the nail. The hook Q is attached to the bar K by a setscrew, so that it can be adjusted as desired. S is an adjustable cutter, attached to the block F, so that the hook Q causes the point of the nail, when it is drawn to the center, to strike it and cutoff the sharp point of the nail at the place indicated by the line at the point of Fig. 6.

When the arm 0 is thrown down and carries the cutters to the nail to cut the point, it also vibrates the lever I and throws back the bar K, which draws the hook Q against the point of the blank, as it is being cut, and draws it to the center of the blank, where it strikes the cutter S and the sharp point is cut off. The spring R throws the bar K with the hook Q forward again ready for another operation, as above described. The cutter E sevcrs the nail Claims.

What I claim, and desire to secure by Letters Patent, is-

1. I claim the cutter S, in combination with the hook Q, when constructed andoperating substantially as and for the purpose specified.

2. I claim the lever I, bar K, hook Q, and arm 0, when arranged and operating substantially as and for the purposes set forth.
